Toner cartridge

A developer supplying device for supplying a developer to a subject to be supplied includes: a housing; and a stirring member rotatable around a rotational axis in the housing, wherein the stirring member includes: a main body that includes a flexible sheet, extends away from the rotational axis, and is in contact with an inner wall surface of the housing; and a cut part formed in the main body, and the cut part projects from the main body when the main body is bent along with rotation of the stirring member.

Developer supplying device and image forming apparatus

A sheet material feeding apparatus includes: a cassette configured to internally contain a sheet material; a push-up plate that is mounted on an inner bottom surface of the cassette and that is a plate on top surface of which the sheet material is mounted; a push-up plate displacement mechanism configured to include push-up plate biasing members and to change a posture of the push-up plate using a biasing force of one of the push-up plate biasing members; a width regulating member configured to be displaced in a width direction intersecting with a feeding direction and to regulate a position of the sheet material; and a biasing member selecting mechanism that includes a switching unit configured to switch application and release-application of the biasing force of one of the push-up plate biasing members to a posture change of the push-up plate, in interlocking with displacement of the width regulating member.

An image reading apparatusincludes an image reading portionwhich is unmovably arranged at one side with respect to a document transportation path, a white reference memberfor shading correction which is arranged at the other side with respect to the document transportation path, a cover memberwhich is capable of being opened and closed so as to expose or cover the document transportation path, and a driving unitwhich changes a posture of the white reference memberbetween an operating posture at the time of the shading correction and a non-operating posture. The white reference memberis attached to the cover member. Further, the white reference memberand the driving unitare related to each other such that the white reference memberis not made into the operating posture in conjunction with an opening operation of the cover member

Image reading apparatus provided with a white reference member for shading correction

A toner supply container has a container body and a conveyance member rotatably arranged inside the container body and which conveys toner toward a discharge opening of the container body when driven to rotate by external force. The conveyance member includes a cylindrical rotary body and a screw blade member wound around the cylindrical rotary body so that the screw blade member stands on an outer circumferential surface of the cylindrical rotary body. The inner surface of a bottom wall of the container body includes a cylindrically curved surface identical to a part of a circumferential surface of an imaginary cylinder whose axis is substantially the same as a rotation axis of the conveyance member. A curvature radius of the cylindrically curved surface is set so the conveyance member rotates in a state where an outer circumferential edge of the screw blade member substantially slides on the cylindrically curved surface.

Toner supply container and image forming apparatus

An image forming apparatus to prevent that the reception operation is interrupted. The image forming apparatus having a cassette for storing sheets, detecting member for detecting the quantity of sheets in the cassette, recording portion for recording images on a sheet, and controler for prohibiting the recording image by the recording portion when the detecting member detects a quantity of sheets that is less than a predetermined quantity.

Image forming apparatus

An image projecting apparatus for projecting on an image receiving body an image on a microfilm incorporated in a cartridge is disclosed. This apparatus is provided with a cartridge loader for supporting a container for accommodating a plurality of cartridges. The cartridges in the container are disposed toward the cartridge holder provided for the image projecting apparatus to allow search of the microfilms held therein. The cartridges holding microfilms which have undergone the search are discharged from the cartridge holder. When the cartridge loader is adapted to allow attachment thereto of one container, the cartridges are taken out of the container and, after completion of the retrieval, the cartridges are returned to the container. When the cartridge loader is arranged to permit detachable attachment thereto of a first container for accommodating unsearched cartridges and a second container for accommodating searched cartridges, the cartridges which have undergone the search are returned to the second container after the cartridges in the first container have been attached to the cartridge holder and subjected to the search. When the cartridges in the first container are emptied, the first container is located at the position formerly occupied by the second container.
